An insight into volcanoes – what they are, what lava is and how they erupt.
This paper discusses the phenomena of the volcano. It describes the constituent elements of lava and the different kinds of lava that exist. It analyzes how the lava is ejected from the volcano and the effect it has on the surrounding environment.
“The makeup of magma determines how it moves, and magma with less than 55 percent silica (basalt) flows easily, while magma with more than 70 percent silica (rhyolite) flows with greater difficulty. Low-viscosity basaltic lava involves the rapid escape of gas which produces fountains of incandescent lava in blobs and drops. Such magma is often fluid enough when it reaches the ground to coalesce and form lava flows. The more high-viscosity rhyolite lava is such that gas cannot readily escape unless there is sufficient pressure. ”
